Centriolar cap proteins CP110 and CPAP control slow elongation of microtubule plus ends.

Centrioles are microtubule-based organelles required for the formation of centrosomes and cilia. Centriolar microtubules, unlike their cytosolic counterparts, are stable and grow very slowly, but the underlying mechanisms are poorly understood. Here, we reconstituted in vitro the interplay between the proteins that cap distal centriole ends and control their elongation: CP110, CEP97, and CPAP/SAS-4.

The interactive role of microRNA and other non-coding RNA in hepatitis B (HBV) associated fibrogenesis.

One of the outstanding features of chronic hepatitis B infection (CHB) is its strong association with liver fibrosis. CHB induced inflammation and injury trigger multiple biochemical and physical changes that include the promotion of a wide range of cytokines, chemokines and growth factors that activate hepatic stellate cells (HSCs) CHB induced activation of hepatic stellate cells (HSCs) is regarded as a central event in fibrogenesis to directly promote the synthesis of myofibroblasts and the expression of a range of materials to repair injured liver tissue. Fibrogenesis is modulated by the mainstream epigenetic machinery, as well as by non-coding RNA (ncRNA) that are often referred to as an ancillary epigenetic response to fine tune gene expression.

PARP12-mediated ADP-ribosylation contributes to breast cancer cell fate by regulating AKT activation and DNA-damage response.

Breast cancer represents the primary cause of death of women under 65 in developed countries, due to the acquisition of multiple drug resistance mechanisms. The PI3K/AKT pathway is one of the major regulating mechanisms altered during the development of endocrine resistance and inhibition of steps in this signalling pathway are adopted as a key strategy to overcome this issue. ADP-ribosylation is a post-translational modification catalysed by PARP enzymes that regulates essential cellular processes, often altered in diseases.

C1orf115 interacts with clathrin adaptors to undergo endocytosis and induces ABCA1 to promote enteric cholesterol efflux.

C1orf115 has been identified in high-throughput screens as a regulator of multidrug resistance possibly mediated through an interaction with ATP-dependent membrane transporter ABCB1. Here we show that C1orf115 not only shares structural similarities with FACI/C11orf86 to interact with clathrin adaptors to undergo endocytosis, but also induces ABCA1 transcription to promote cholesterol efflux. C1orf115 consists of an N-terminal intrinsically disordered region and a C-terminal α-helix.

Autophagy Attenuates Oxidative Stress-Induced Collagen Degradation in Vaginal Fibroblasts: Implications for Pelvic Organ Prolapse.

Introduction And Hypothesis: The relationship between autophagy and pelvic organ prolapse (POP) remains unknown. The aim of this novel experimental study, utilizing tissue samples derived from women undergoing gynecological surgery, is to investigate the role of autophagy in mitigating collagen degradation in human vaginal fibroblasts induced by oxidative stress, with particular emphasis on its implications in the pathogenesis of POP. Exploring the role of autophagy in protecting against collagen degradation and cellular senescence in human vaginal fibroblasts under oxidative stress may offer new insights into therapeutic strategies for conditions such as POP.

RNA-Seq transcriptomic landscape profiling of spontaneously hypertensive rats in youth treated with a ARNI versus ARB.

Angiotensin receptor-neprilysin inhibitor (ARNI) and angiotensin II receptor blockers (ARB) are antihypertension medications that improve cardiac remodeling and protect the heart. However, at the early stage of hypertension, it is still unclear how these two drugs affect the transcriptomic profile of multiple organs in hypertensive rats and the transcriptomic differences between them. We performed RNA sequencing to define the RNA expressing profiles of the eight tissues (atrium, ventricle, aorta, kidney, brain, lung, white fat, and brown fat) in spontaneously hypertensive rats (SHRs) and SHRs treated with ARNI or ARB.

Hypopituitarism Screening in Patients with Traumatic Brain Injury in the Primary Care Setting at the Minneapolis Veterans Affairs Health Care System.

Introduction: Traumatic brain injury (TBI) is a significant health issue among veterans and poses a substantial risk for pituitary injury. Consensus guidelines recommend that patients who have sustained a TBI should undergo a baseline pituitary hormonal evaluation after the primary brain insult. Patients with abnormal screening test results or with symptoms of hypopituitarism should be referred to endocrinology for a full assessment.

Selenium Nucleophilicity and Electrophilicity in the Intra- and Intermolecular SN2 Reactions of Selenenyl Sulfide Probes.

Chalcogenide exchange reactions are an important class of bimolecular nucleophilic substitution reactions (SN2) involving sulfur and selenium species as nucleophile, central atom, and/or leaving group, which are fundamental throughout redox biology and metabolism. While thiol-disulfide exchange reactions have been deeply investigated, those involving selenium are less understood, especially with regards to the polarised selenenyl sulfides RSe-SR' even though the directed reactivity of selenenyl sulfides is biologically crucial for selenoenzymes such as thioredoxin reductase (TrxR) and glutathione peroxidase (GPx). Synthetic methods to create asymmetric selenenyl sulfides with high regiochemical purity only emerged over the last five years; this functional group has already demonstrated powerful applications to cell biology, through probes for molecular imaging (e.

Palladium-Catalyzed Oxidative Allene-Allene Cross-Coupling.

Direct cross-coupling reactions between two similar unactivated partners are challenging but constitute a powerful strategy for the creation of new carbon-carbon bonds in organic synthesis. [4]Dendralenes are a class of acyclic branched conjugated oligoenes with great synthetic potential for the rapid generation of structural complexity, yet the chemistry of [4]dendralenes remains an unexplored field due to their limited accessibility. Herein, we report a highly selective palladium-catalyzed oxidative cross-coupling of two allenes with the presence of a directing olefin in one of the allenes, enabling the facile synthesis of a broad range of functionalized [4]dendralenes in a convergent modular manner.

Key glycometabolism during oocyte maturation and early embryonic development.

In recent decades, it has become increasingly clear that mammalian gametes and early embryos are highly sensitive to metabolic substrates. With advances in single-cell sequencing, metabolomics, and bioinformatics, we now recognize that metabolic pathways not only meet cellular energy demands but also play a critical role in cell proliferation, differentiation, and fate determination. Investigating metabolic processes during oocyte maturation and early embryonic development is thus essential to advancing reproductive medicine and embryology.

Rectification of planar orientation angle switches behavior and replenishes contractile junctions.

In the early Drosophila embryo, germband elongation is driven by oriented cell intercalation through t1 transitions, where vertical (dorsal-ventral aligned) interfaces contract and then resolve into new horizontal (anterior-posterior aligned) interfaces. Here, we show that contractile events produce a continuous "rectification" of cell interfaces, in which interfaces systematically rotate toward more vertical orientations. As interfaces rotate, their behavior transitions from elongating to contractile regimes, indicating that the planar polarized identities of cell-cell interfaces are continuously re-interpreted in time depending on their orientation angle.
